title: "Convert CIELAB to the polar representation (polarLAB)"
---

### Description

Converts colors from the CIELAB color space into its polar
representation (`polarLAB`).
Inverse function of [polarLAB_to_LAB](colorspace.colorlib.colorlib.polarLAB_to_LAB.qmd).

### Usage

<pre><code class='language-python'>colorlib.LAB_to_polarLAB(L, A, B)</code></pre>

### Arguments

<dl class="pyp-list param-list">
  <dt style = "white-space: nowrap; font-family: monospace; vertical-align: top">
   <code id="colorspace.colorlib.colorlib.LAB_to_polarLAB:L">L</code><code class="argument-class">numpy.ndarray</code>
  </dt>
 <dd>Values for the `L` dimension.</dd>
  <dt style = "white-space: nowrap; font-family: monospace; vertical-align: top">
   <code id="colorspace.colorlib.colorlib.LAB_to_polarLAB:A">A</code><code class="argument-class">numpy.ndarray</code>
  </dt>
 <dd>Values for the `A` dimension.</dd>
  <dt style = "white-space: nowrap; font-family: monospace; vertical-align: top">
   <code id="colorspace.colorlib.colorlib.LAB_to_polarLAB:B">B</code><code class="argument-class">numpy.ndarray</code>
  </dt>
 <dd>Values for the `B` dimension.</dd>
</dl>

### Return

<code>list</code>: Returns corresponding polar LAB chromaticities as a list of
`numpy.ndarray`s of the same length as the inputs (`[L, A, B]`).
